The Lowdown

Alright folks, Rusty here. Let’s cut through the noise and talk about what’s actually brewing for Jaconé.

We’ve got a bit of a mixed bag over the next couple of weeks, but there’s a real standout tucked away in the second week. The water is sitting at a warm 73°, which is a touch warmer than what we usually expect this time of year – almost one and a half degrees above normal, so it’s a nice little bonus when you’re in the water.

The first week is a bit of a grind, to be honest. The swell is there, but the wind is a constant battle. Friday the 14th kicks off with a solid 7ft south swell, but it’s a cross-on mess with a WSW wind making it choppy. The combined energy is a massive 1526, so there’s plenty of power, but it’s not pretty. Saturday the 15th is a little cleaner with the wind shifting cross-off, and the swell hangs around 8ft to 8ft from the SSE. That’s a solid wave height, but at 8ft it’s getting into the “experts only” territory, especially with that 13-second period. It’s a proper groundswell, so it’ll be hitting the banks with some serious push, but it might be a bit too much for the average surfer unless you're on a point or reef. Sunday morning the 16th looks the best of the early days – a clean 5ft S swell with a fresh offshore from the ENE. That’s a real window of clean, offshore waves, but the energy drops way down to 720, so it’s not as punchy. After that, the wind turns onshore again and the swell drops off, leaving us with a few days of small, weak E swells under 4ft through the middle of the week. The period is short, around 7 seconds, so it’s just windswill.

Now, hold on to your board, because Tuesday the 25th is the real deal. The morning brings a 5ft SSW groundswell with a 12-second period, and the combined energy is a solid 642. The wind is a light cross-off from the ENE, which means clean, lined-up waves. The forecast calls for “very good surf conditions” and that’s the only time we see that. This is the standout. It’s not the biggest swell of the period, but the quality of the wave, the clean wind, and the consistency all point to this being the session to circle on your calendar. It’s a solid intermediate wave, so it’s not just for the hardcore crew. After that, the wind gets messy again and the swell fades out through the end of the month.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
